TANK-HEATER.

Specication of Letters Patent.

Patent-ea oet. 2,1917.

Application led November 17, 1916. Serial No. 131,838.

To all 'whom t may concern:

Be it known that I, NELSON D. RraMEN- SCHNEIDER, a citizen of the UnitedStates, State Center, in the county of Marshall andState'of Iowa, haveinvented certain new and useful Improvements in Tank-Heaters, of 'whichthe following is a To the attainment of I so . chamber, which may sureand the edge of the chamber for secur-y d -through specication. j

' This invention relates to improvements in tank heaters and one of theobjects of the same is to provide an improved device of this characterwhich will be simple, durable and cheap in construction and elfectlveandv one in which liqeliicient in operation, and

employed uid fuel such as kerosene may be as a heating medium.

these ends and the accomplishment of other new and useful objects aswill appear, in the features of novelty in substantially theconstruction, combination and arrangement of the several partshereinafter more fully described and claimed and shown in theaccompanying drawing, illustrating the inention and in whichcharacterconstructed 1n accordance with ing the same applied to a tank. v Fig. 2is a detail horizontal sectional view taken on line 2-2, Fig. 1.

Fig. 3 is a view similar to Fig. 1 of a portion of the heater, showing amodied orm thereof.

Referring more particularly to the drawing, the numeral 10 designates aheating be of any Vdesired size and configuration, and constructed ofany suitable material.

The bottom of the chamber is open and a closure 11 is provided thereforwhich rests against the open edge of the .bottom ofthe chamber and agasket 12 of any suitable material may be interposed between the cloinga fluid tight joint. The closure is hel in position in any suitablemanner such as by means of fastening devices 13, which permit theclosure to be readily removed when desired. Suitable supports 14 mayalso be provided, if desired, to hold the chamber above the bottom ofthe tank 15, although these supports are not necessary.

Arranged within the chamber 10 is a lamp 16 preferably adapted for theuse of kerothe invention consists gure 1 is a vertical longitudinalsec-k tional view of an improved device of this 28 of the'pipeterminating sene and the lamp is provided with a wick adjusting stem 17to which is secured a gear 18.

. Projecting through the upper end of the chamber is a .pipe 19, whichextends for some distance above the chamber and terminates within thechamber. A shaft 20 passes through this pipe 19 and one end of the shaftis journaled in a suitable bearing 21, while the other extremity 22 ofthe shaft projects beyond the extremity of the pipe 19 and a detachablehandle 23 the extremity of the shaft.

A ear 24 is also connected with the shaft within the chamber 10 and thisgear meshes with the gear 18 so that when the shaft 2O is rotated by thehandle 23, the gear 18 and the wick adjusting stem 17 will be actuated,to raise and lower the wick.

Air is supplied to the interior of the chamber 10 to support combustionby means of a suitable air supply pipe 25, which projects into the tankand preferably terminates at a point below the flame of the lamp.

The other extremity 26 of the pipe 25 is located somel distance beyondthe chamber and above the water level in the tank.

Another pipe 27 similar to the pipe 25, projects into the chamber 10,the extremity preferably at a point above the flame, so as to receivethe gases and products of combustion from the chamber, and which gaseswill be discharged through the extremity 29 of the pipe 27, and whichextremity 29 is also located above the water level of the tank. Theheater is secured in position in the tank and held submerged in anydesired or suitable manner, such as by means of anchor rods 30, whichengage suitable anchors 31 in the bottom of the tank and also ears orprojections 32 on the chamberlO. Suitable thumb screws 33 may beprovided on the anchor rods 30 to permit ready removal of the heater.

is connected to Oil is supplied to the lamp preferably a pipe 34,*whichextends into the chamber 10 and has communication with the oil reservoirof the lamp. This pipe 34 ter-` minates abovethe water level in the tankand is closed' by a cap 35, so that when it is desired to fill the lamp,the cap 35 may be removed and the oil passed through the pipe 34 to thereservoir. A float 36 may be provided which has an indicator 37connected thereto, and this indicator extends through llt the pipe 34 sothat the operator may readily ascertain the quantity of oil in the lamp.

With this improved construction it will be manifest that after the lampis once lighted and the heater secured in position in the tank, the lampcan not only be controlled from the outside of the tank Without removingthe heater, but the lamp may also be lled While the tank is submergedand the operator can readily ascertain the amount of oil in the lampWithout removing eater.

The air being supplied through the pipe 25'to the chamber 10 supportsthe combustion of the lamp and the gases and'smoke Will pass out of thepipe 27. j i

In the form of the invention shown in Fig. 3, a coil 38 is providedWithin the chamber 10. This coil has an inlet 39 opening through theWall ofthe chamber and .an outlet 40 opening throu chamber and the coilbemg in communication with the tank, the Water will flow into the coilwhich is arranged around the Wall of the chamber inside thereof, andpass out of the outletetO. This will not only assist in heating theWater but will induce a cir culation of the Water in the tank. l

'While the preferred forms of the invention have been herein shown anddescribed,

it isy to be understood that many changes may be made in the details ofconstructionan in the combination and arrangement of the several partsWithout departing from the spirit of this invention.

VWhat'is claimed as new is l 1. A tank heater embodying a heatingchamber, a burner Within the chamber, a

.feed pipe for the burner extending through the 4top of the chamber, anupright air inlet pipe extending into the chamber through the toplthereof and terminating adjacent the burner, an upright air outlet pipealso extending through the top of the chamber and terminating adjacentthe burner, the ends of the air ppes Within the chamber terminating indi erent horizontal planes, a burner controlling shaft extending throughthe top of the chamber, and an upright casing for the shaft, said casingextending through the top of the chamber.

2. A tank heater embodying a heatingv the chamber, a L

chamber, a burner Within feed pipe for the burnerextending through thetop of the chamber, an upright air inlet pipe extending into the chamberthrough the top thereof and terminating adjacent the burner, an u rightair outlet pipe also the top of .the chamber extending throug gh theWall of the,

and vterminating adjacent the burner, the ends of the air pipes Withinthe chamber terminating in different horizontal planes,
